This discussion clarifies the rules around GST invoice numbering at the start of a new financial year. While it's permissible to continue an existing invoice series (e.g., ABC/20-21/LBR/34), ensuring each number is unique to the financial year, it is generally recommended to start the new financial year's invoices from serial number 0001 for better practice.
If last invoice number in FY 19-20 was ABC/19-20/MAR/33, then in FY 20-21, can the series be started with ABC/20-21/LBR/34 or is it mandatory to start the series with serial no 1?

Thanks Dileep Sir, Just to confirm as you said it should be unique, that means invoice number ABC/20-21/LBR/34 can be taken from FY 20-21?
